Solr configuration for queries

[Anshul jain <an...@epfl.ch>]

Hi,

I need to configure solr, such that it doesn't do any fancy stuff like
adding adding wildcard characters to normal query, check for existing
fields, etc.

I've modified lucene code for Term queries(can be multiple terms) and I need
to process only term queries. But solr modifies queries and converts them to
range queries. I just need that solr simply pass the query to lucene
IndexSearcher and do nothing else in between. Is it possible?

Cheers,
Anshul

Not sure what you mean but you can always escape query special characters
and then enclose whatever passed in double quotes. This way you'll have
it treated as phrase each time.

http://lucene.apache.org/java/2_4_0/queryparsersyntax.html
Scroll to 'escaping special characters'

+ - && || ! ( ) { } [ ] ^ " ~ * ? : \

Cheers

i'm not entirely sure i understand what you mean ("check for existing 
fields" ?!?!) but you may want to take a look at the FieldQParserPlugin, 
it sounds like it might meet your needs -- if not, it will probably serve 
as a good starting point for implementing your own QParser to generate 
exactly the type of query you want based on the input.
